Justin Welby, Archbishop of Canterbury, refused to reveal whether he would officiate at the royal wedding, but said their decision to marry in the the 15th-century chapel was based on a commitment to faith.

"I am very, very sure after conversations that this is no tick-box exercise," he told the BBC's Today program which was broadcast from Lambeth Palace on Thursday.

"There is a profound sense of commitment, of seriousness, both about faith and their lives together, which is quite inspirational," he said. "It's important because people look at it and see a model of how two people commit their lives to one another before God in the presence of millions of people. It's always a beautiful moment, every wedding is profoundly beautiful. Even when you drop the rings it's still a very moving wedding."

Welby revealed he was looking forward to the big event, saying it would be "fun."

The couple, who announced their engagement in November, will live in Nottingham Cottage in the grounds of London's Kensington Palace, the official residence of the Duke and Duchess of Cambridge.

Harry and Markle first met on a blind date in July 2016, and the prince proposed on a "cozy night" in early November at Nottingham Cottage.

"It was so sweet and natural and very romantic. He got down on one knee," she said. "As a matter of fact, I could barely let you finish proposing. I said, 'Can I say yes now?'"

The engagement ring, designed by Prince Harry, features a diamond from Botswana accompanied by two smaller diamonds from Diana's jewelry collection.
